YL promotes proliferation of hippocampal neural stem cell in vitro. (a,b) Co-immunofluorescence staining of BrdU (red), nestin (green), and DAPI (blue). Hippocampal neural stem cell proliferation was evaluated by counting BrdU and nestin-positive cells in the culture (n = 4). Values are expressed as the mean ± S.E.M. Different characters represent significant differences (P < 0.05) among groups by the nonparametric Mann–Whitney U test. Scale bar, 100 μm.
